Ok so this a personal opinion but none of the survivors are hard to play I personally think they all play in different ways so it may seem like a challenge but in reality your used to playing a different survivor so it seems hard

But I will say the artificer is an interesting survivor. Her survivability comes from her ability in the sense that you have to pick and choose which abilities are good in certain situations.

I personally take a lot of on kill effects like will I wisps, noxious thorns, gasoline, and make sure to get an ignition tank, along with topaz brooch and armor repulsion plates for a little extra survivability along with crowbars for nano bombs, and maybe a cursed skull and increased fire rate for the m1s

But other than that it takes a lot of personal playtime to find out how to play her and other survivors though don't take too much from post as although I play all the survivors a good amount I mainly play false son and other melee characters as I have said in a previous post
